Specification of Letters Patent.

Patented. J uly 5, 1921.

Application filed. September 2, 1920. Serial No. 407,685.

'To all whom it may concern.

This invention relates to handle brackets I or arms, and has for its object a handle bracket so designed that in connection with the screw that secures the handle to the bracket an eiiective thread lock is secured which prevents the screw from turning out.

Furthermore, practically the entire load of the handle and any load that may be placed upon it is carried upon the larger portions of the handle and screw and taken ofl' the threads. This will be better explained when the construction is explained in detail.

In the drawings,-

1Figure '1 is a front elevation of the ban d c.

Fig. 2 is a cross section of the same.

Fig. 3 is a section on the line 3-3 of Fig 2.

The handle here shown is a handle by which a portable washing machine 6 is moved about. This is simply shown as an example. Obviously the invention is capable of use wherever a handle, or for that matter any similar member, is employed. The handle comprises a bar a (preferably of wood) of circular'cross section (but, of course, the cross section is immaterial). The bracket or fixture comprises a base 00- and a spindle portion 0 which is pyramidal for the main portion of its length but which at the zone where it merges into the base is formed into a cylindrical portion at for artistic effect. However, the outer end of the spindle is formed into a cylindrical portion 6 for a distinct functional purpose, as will be explained. The cap screwf runs through threads prepared in the wooden bar a and also into a tapped cavity g running coaxially into the end of the spindle. From Fig. 2 it will be seen that the wooden bar a is drilled for the threaded shank of the screw and that this drilled hole is also counterbored in two sizes, one for the cylindrical load-carrying portion 6 of the spindle and the other to receive the head it of the The parts are assembled together by screwing the cap screws 7 into the bara and then the brackets are turned on to the protruding ends of the screws untilthey draw tightly on thecap screws so as to jam the cap screw threads tightly into engagement with the threads of the bar a. In thisrespect the bracket acts in precisely the same way as the jam-nut does to look a nut to the threads on which it runs. Hence when the brackets have been turned so as to hold tightly on thescrews to jam them into engagement with the threads, thewhole assembly acts as a thread lock to prevent the screws 7 from turning out. This is aparticularly secure one because the jamming members cannot possibly themselves become loose by turning for the reason that after they have been so turnedto jam the threads of the screws and the bar, the bases of the fixtures are bolted to the side or supporting wall I; by the bolts and nuts 2', for example. Of course, any other suitable fastening means could be used.

The load of the bar a or any pressure exerted. upon it is practically all taken by the large cylindrical portion e at the end of the spindle and the cylindrical head 7b of the cap screw for the threads cut them selves free of the load, and hence the threads are in no way impaired by being subjected to the load. vThe load-carrying--portion .e of the sprindle being circular in cross section, permits the same to be inserted in the counterbore and at the same time turned to effect the locking action already described- What I claim is:

In a handle having in combination, a handle member-bored to receive the shank of In testimony whereof I aifix m si nature.
